Hey all, so i have a trich problem. I definitely do need to completely sterilize my area before i start up some more tubs. But heres my process: I start out by making my quart sized jars, i made self healing lids with professor pinheads tek w polyfil and RTV sealant. I buy LC syringes from a trusted vendor and noc up white millet (Making sure to follow proper sterile procedure). I wait until every jar is fully colonized before i decide to start up tubs. At this point, everything seems to be chillin. My substrate consists of about 50% coco coir, 30% worm castings and 20% verm. I premix all of that and throw it in jars where i pasteurize in the pressure cooker @10psi for about 1hr20m. I let those cool overnight. Now the thing is, once i went to start up my tubs i would do it in an open area without spraying any type of “air sterilizer”, which mightve been one of my problems. i dont have a flow hood yet but i actually kind of made my own cheap version where i took a fan and duct taped on two air filters front and back, i hooked up a pic for reference. Next time i will build everything in front of that and see if it helps out. anyway, when i build my tubs i make sure im clean. Just showered, use gloves and mask and wiping everything down with iso. I dont modify my tubs at all, so once theyre put together i set em and *try to* forget em! I dont open up the tubs at all during colonization as Ive read changing the stable environment is no bueno. But i do make sure to keep tabs and check for any type of discoloration. My tubs will start out completely fine, flourishing and getting a nice dense layer of mycelium on top, water droplets and everything, i get so excited bc it looks so awesome, just to get hit with trich about 10 days in. Its been discouraging but i know that once i get my sterilization/technique down i got this. Thanks for the help yall i will gladly take and appreciate any type of advice or constructive criticism. Bless up!
